External scaffolding is an important temporary facility for construction projects, mainly used in three aspects: firstly, during the construction phase of the main structure, it serves as an operating platform for workers to install and remove the outer formwork of columns, walls, and beams; The second stage is the exterior wall decoration stage, which provides a platform for exterior wall construction work; Thirdly, it serves as a safety protection facility for floors and roof edges.
During the entire construction period of the external scaffolding, it not only provides a working surface for the operators, but also plays a core role in ensuring the safety of high-altitude operations.
Among them, the protective height setting of the top of the scaffold pole above the roof directly determines the reliability of the roof operator’s fall protection, which is a key content that cannot be ignored in the safety technical control of scaffolding.
